    Unfortunately Snoopy, once ligaments are damaged, they are hard to repair and rarely return to what they were before the injury. As i recommend to most of my patients with unstable knees, make sure you keep your hamstrings , quadriceps and calf muscles strong. When the ligaments are weak, the muscles play a huge part in providing your knees with stability. You can also wear a knee brace while exercising. A chiropractor can also recommend some great exercises for you to strengthen your leg muscles and provide your knees with stability.

    It can give way when you have had an injury to the knee, a traumatic injury, it can be a sign or symptom of ligament instability, ligament damage. Usually that is the cause.

    Also, when there is also a lot of muscular atrophy around the knee muscles, when someone is very weak around the core muscles that is what happens as well.
